John,

Thanks for all that.

(and a 2kg class Makita or similar will be a complete revelation
after the Ferm!)

In what respect?Â* The Ferm did - everything I needed it to.Â* It was
more than powerful enough, easy to handle, and required little
maintenance.

How will a Makita or similar be better than that?

IME In several ways... (although this may depend on which Ferm you have
- the early ones were very crude - the later ones slightly less so)

Firstly its lighter to hold and probably a better ergonomic design - so
less fatigue using it.

It will have a chuck that allows you to rotate a chisel bit to an
orientation of your choice and then lock it in that position. So
chiselling a straight cut is much easier, and you can also do it in any
direction while holding the drill at an comfortable angle. (many of the
cheapies allow a bit to wander in rotation when in roto stop mode)

It will have a better speed control, allowing you to chisel very gently
to start with if you need - say delicate cutting through a plaster skim
coat while edging round where you want to cut a socket back box recess.

It will run much cleaner - you just need the occasional spot of grease
on the shank of a bit (say once every twenty bit swaps), there is no
reservoir that needs refilling, and it won't gob grease over what you
are working on when it gets hot.

Other than that you get a nice long (12' - 16') rubber flex, and a motor
rated for continuous use.



Horses for courses, though, my ancient Ferm SDS was a fraction of the
price of a Makita. No chuck lock as you say, but long rubber flex and it
appears to have a continuous rated motor. I do, generally, buy more up
market tools these days but I reckon the Ferm is OK for "building site"
type jobs.
